Penelope Athena is the couple’s second daughter. Their first child, Alice, is 5.

It was back in April, while appearing on “The Oprah Winfrey Show,” that Tina first confirmed she was pregnant.

The new baby will give husband Jeff a second chance at diaper duty.

In GQ’s May issue, the “Bossypants” author said her husband was good at everything to do with Alice, everything but diaper duty.

“My husband was really good about helping out. The problem was diapers. He never got past the poop,” Tina previously told the mag. “He would do these [gagging noise] ‘Oh God, I’m gonna vomit.’ Never got over it.”
